Summer Travel Causes Numerous Swiss Road Jams
Holiday Traffic Causes Significant Delays
During the summer holiday period, including August 23, 2026, a significant travel surge and numerous traffic jams are expected on Switzerland's main traffic arteries and international transit routes. North-South connections towards Italy and access roads to popular holiday regions are particularly affected.
Gotthard and San Bernardino Heavily Congested
The classic holiday routes via the Gotthard and San Bernardino tunnels experience significant traffic disruptions. Vehicles sometimes queue for several kilometers in front of the tunnel entrances. Stop-and-go traffic also occurs on the A2 between Basel and Lucerne, and on the A13 in the canton of Grisons. Travelers should expect delays of several hours.
The increased traffic volume affects not only transit routes. Regional connections to holiday areas in the Alps and Ticino are also overloaded. Commuters and day-trippers must also account for longer travel times.
Recommendations to Avoid Traffic Jams
Traffic experts advise travelers to use off-peak hours. Early mornings or late evenings offer better passage conditions. Those with flexibility should avoid peak travel times on weekends and at the start of holidays. Using alternative routes can also reduce time losses.
Traffic information services recommend checking the current traffic situation before starting a journey. Mobile apps and radio traffic reports provide timely updates. In case of long traffic jams, travelers should carry sufficient drinks and provisions. Families with children particularly benefit from good preparation.
International Routes Also Affected
Significant delays also occur not only in Switzerland but also on approach roads from Germany, Austria, and France, as well as on Italian motorways. Holiday periods coincide in several European countries, further exacerbating the traffic situation.
Swiss authorities point out that the traffic congestion will likely continue for several more days. The situation will only ease after the main travel wave ends in late August. Until then, motorists must expect repeated traffic jams and longer travel times.
For travelers dependent on cars, patience remains essential. Those who can should switch to public transport. Swiss Federal Railways offer a dense network of connections to key destinations, even during the holiday period.
